What does "HH" mean?

HH stands for "Hollow Handle", which means
that the item has been made with a hollow sterling
silver handle, and a stainless steel utensil has been
inserted into it. Generally, the dinner knife handle
is used for serving pieces, and a smaller version
is used for the Butter Knife and Butter Spreader.
